    I picked up your article on a Google search. This is a really well written step by step article. I had contacted the Geek ***** about this error and what they quoted me to fix the error was pretty spendy, plus I’d be without my computer for a few days. Now I can just fix it myself instead. 🙂

    i was facing the error 1721 problem when trying to install EastWest Symphonic Orchestra on my windows 8.1 machine. I tried all the above of which none worked for me…
    i found the solution in gearslutz:

    Open up regedit, navigate to HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System, and change the value of EnableLua to 0. Close, restart, and install. Once done, open regedit again, change it back to 1, then restart.
